I have my router set up so that each of my machines has its Mac address reserved, including my Droid 2. I set up wifi on the droid 2 a couple of weeks ago and it connected every time and worked perfectly for a few days. But ever since it will not connect. It says "Connecting...." and then immediately says "Disconnected". I can connect to my neighbor's router which is completely open, but can no longer connect to mine even though I could for a few days. Someone told me I should go into the Advanced menu of the WiFi settings and select a different peer to peer channel. Every time I do that it says, "Sorry! The application Settings has stopped unexpectedly" and gives me a "Force Close" button. I've tried uninstalling several applications and shutting down the system and removing the battery. Nothing works. I don't want to open up my router to any machines other than my specific mac addresses, which did work for a few days. Does anyone know how to get this system working with wifi so that it is reliable for more than 72 hours?
